Shop parts for a 2017 Husqvarna FE450HQ Dirt Bike.

The 2017 Husqvarna FE450HQ is designed for high-performance off-road riding and features a precise intake system that relies on a clean, well-maintained air filter for optimum power and engine longevity. Below you will find a MotoSport-exclusive, step-by-step guide for air filter cleaning and replacement, along with tips specific to this model.

Why Air Filter Maintenance is Critical

  • Engine Protection: The FE450HQ’s engine breathes massive volumes of air – a clogged or dirty filter means risk of dirt ingestion, power loss, and increased wear.
  • Performance: Consistent air flow ensures the throttle response and horsepower the 450cc single is built for.
  • Longevity: Proper filter care helps this big-bore Husqvarna maintain smooth running and avert costly rebuilds.

How to Remove the Air Filter on the 2017 Husqvarna FE450HQ

  1. Remove the Seat: Release the rear-fastener and pull up on the seat to access the airbox.
  2. Remove the Airbox Cover: Pull the cover sideways then lift forward—the FE450HQ's cover is designed for tool-free removal, allowing easy access even at the track or trailhead.

Cleaning The Air Filter

  1. Take Out the Filter: Carefully detach the filter from the airbox intake. Pay attention to avoid debris falling into the throttle body.
  2. Pre-Clean: Tap the filter gently to remove loose debris.
  3. Wash: Submerge and agitate the filter in an approved filter cleaner or mild detergent mixed with warm water. Rinse thoroughly from the inside out. Never use gasoline or solvents—these can break down filter glue and foam.
  4. Dry Completely: Squeeze out excess water (do not twist.) and allow the filter to air dry fully before oiling.
  5. Inspect: Check for tears, split seams, or degraded foam. Replace immediately if damaged.

Oiling & Reinstalling the Filter

  1. Oil: Apply high-quality foam filter oil evenly, ensuring the entire surface is tacky but not dripping.
  2. Install: Refit the filter carefully onto the intake flange, ensuring a proper seal around the entire perimeter – any gaps can let unfiltered air into the engine.
  3. Reattach Airbox Cover and Seat: Snap the airbox cover back into place, followed by the seat, making sure all fasteners are secure.

Replacement Guidelines

  • Clean After Every Ride: For dusty or wet conditions, clean immediately after each outing.
  • Replace When Necessary: Replace the filter at least every season or sooner if damaged. The FE450HQ's power and air demand mean frequent inspection is critical.

Special Considerations for the 2017 FE450HQ

  • Unique Airbox Design: Husqvarna's unique airbox has a thoughtful splash guard; however, improper seating will still risk bypass. Always double-check placement by visually inspecting the seal on all sides.
  • Model-Specific Fitment: Only use air filters listed specifically for the 2017 FE450HQ to ensure exact fit and optimum filtration & airflow.
  • Cross-Check after Reinstalls: Due to the robust throttle response and engine vibrations, verify filter retention before each ride.

MotoSport Pro Tip

Keep a spare, pre-oiled filter in your gear bag. Fast swaps mean less downtime and no excuse to ride with a clogged or wet filter.
